Definitions

  • the present invention relates to a circuit for correcting the power factor.
  • Such circuits are also known as “charge pumps” or “pump circuits". They are used, for example, to comply with the IEC 1000-3-2 standard, in which electric utilities have defined the permissible mains current harmonics. Accordingly, the removal of high-frequency energy from the power grid is not desirable.
  • the mains current which is withdrawn from the network is in the optimum case proportional to the mains voltage.
  • a proportionality between mains current and mains voltage enables the maximum energy transfer per given cable dimensioning. Reactive currents, which would occur in the event of disproportion between mains voltage and mains current, would cause line losses, which would additionally stress the lines and therefore lead to interference with other consumers.
  • Such power factor correction circuits are used for ballasts for operating gas discharge lamps.
  • the present invention is based on a prior art as it is known from the article of W. Chen, F. Lee and T. Yamauchi entitled “An Improved” Charge Pump “Electronic Ballast with Low THD and Low Crest Factor”, published in IEEE Transactions on Power Electronics, Vol. 5, September 1997, pages 867-875 , With reference to the local Fig. 8, this essay was based on the problem, the circuit with respect to the local there Fig. 1 to modify so that the voltage at point A, ie V, (see Representation in the local Fig. 7), constant Hf amplitude has. This would ensure that the energy taken from the grid is proportional to the mains voltage.
  • a disadvantage of the circuit of FIG. 8 of this publication is that the lamp voltage is limited by the diode Da 2 . Therefore, without the interposition of a transformer between the pump circuit and the lamp to be operated, the necessary ignition voltage can not be generated. For mass products such as ballasts for lamps, the additional costs for a transformer are undesirable.
  • the present invention is therefore based on the object, a circuit for correcting the power factor, ie to provide a pump circuit that requires no transformer.
  • a circuit for correcting the power factor ie to provide a pump circuit that requires no transformer.
  • An example of such a circuit is from the article of G. Chae, YS Youn, GH Cho. "High power factor correction circuit for low-cost electronic ballasts", published in Electronics letters, 1997, vol. 33, No. 11, pages 921-922 , refer to.
  • a circuit with a rectifier the input side of which is connected to an AC voltage source and the output side is connected to at least one series connection of a capacitor and a diode, wherein the diode is arranged so that the capacitor from the output signal of the rectifier not through the diode can be charged.
  • It further comprises a first and a second electronic switch connected in series as part of a half or full bridge, each with a freewheeling diode connected in parallel to each switch, wherein the output connection formed by the connection point between the first and second switches on the one hand via the half or full bridge an inductance is connected to a point on the connection of capacitor and diode of each series circuit of capacitor and diode, on the other hand a Forming terminal for a load, wherein the signal at this terminal in operation has substantially higher frequency than the output signal of the AC voltage source. It further has a storage capacitor which is connected in parallel with the two switches, and at least one further diode which is arranged between the storage capacitor and the rectifier such that a discharge of the storage capacitor is prevented by the rectifier.
  • the invention offers on the one hand the advantage of additional degrees of freedom in the dimensioning of the elements of the pump and load circuit by the greatest possible freedom from feedback between the two circuits. It also allows easy adjustability of the lamp power by appropriate dimensioning of the capacitor CS1 and the capacitors CS1, CS2 such that the voltage of the capacitor or capacitors at least once reaches the respective instantaneous value of the feeding, rectified AC voltage, which can be assumed in that, when considering a charging cycle, the rectified AC voltage is constant. Moreover, the energy to be pumped into the load only depends on the capacitance value of the capacitor CS1 and the capacitance values of the capacitors CS1 and CS2. The inductance of the inductor L must or can be small, it must merely be dimensioned so that the electrical switch are not overloaded in terms of electricity and the same is maintained at the voltage 0 (ZVS).
  • a filter is arranged between the inputs of the rectifier, which is arranged when connecting the circuit with an AC voltage source in series or parallel to the AC voltage source. Additionally or alternatively, a filter may be arranged in series or parallel to the output of the rectifier.
  • the circuit comprises a series circuit of diode and capacitor and a further diode.
  • the circuit comprises two series circuits of diode and capacitor and two further diodes.
  • the circuit can be operated in the form of a half bridge or a full bridge.
  • the circuit comprises two further switches, wherein the connection point of the two further switches forms the second load terminal.
  • the circuit comprises two coupling capacitors, wherein the connection point between the two coupling capacitors forms the second load terminal and wherein the series connection of the two coupling capacitors is arranged parallel to the storage capacitor.
  • it may also comprise only one coupling capacitor, one terminal of which forms the second load terminal, its second terminal being connected to one of the two terminals of the storage capacitor.
  • Fig. 1a shows a circuit with an AC voltage source 10, which is arranged in series with a filter 12.
  • AC voltage source 10 the mains voltage can be used.
  • the filter 12 serves to prevent that on the one hand radio frequency energy is removed from the AC voltage source, on the other hand, that high-frequency signals are fed into the AC voltage source. It is therefore a low-pass filter, which can be realized for example as a throttle.
  • AC voltage source 10 and filter 12 are connected to the inputs of a rectifier 14 comprising the four diodes DG1, DG2, DG3 and DG4.
  • the filter 12 can also be arranged parallel to the input terminals of the rectifier, wherein it can then be realized as a capacitor with little effort.
  • the series circuit Parallel to the output terminals K1, K2 of the rectifier, the series circuit consists of a capacitor CS1 and a diode DS1.
  • the capacitor CS1 is connected via a diode DP1 to the series circuit of two electrical switches T1 and T2, which are each connected in parallel freewheeling diodes DF1 and DF2.
  • the connection point of the two switches T1 and T2 is connected on the one hand via an inductance L to the connection point between the capacitor CS1 and the diode DS1 and on the other hand constitutes a connection for the load LD.
  • the load LD is connected to the output terminals of a half-bridge
  • the second load terminal is formed by the connection point of two coupling capacitors CK1, CK2, which are arranged in parallel with the switches T1 and T2.
  • Parallel to the coupling capacitors CK1 and CK2 is in the circuit according to Fig. 1a a storage capacitor CS arranged.
  • the operating frequency of the two electrical switches, which are operated in phase opposition, is high-frequency compared to the frequency of the AC voltage source. For example, 50 kHz compared to 50 Hz, ie, the two transistors are turned on alternately for every 10 microseconds.
  • the switch T2 is turned on, current flows from the rectifier 14 via the terminal K1 through the capacitor CS1 and through the inductance L and the electrical switch T2 to the terminal K2 of the rectifier.
  • the capacitor CS1 and the inductance L are in this case dimensioned so that the capacitor CS1 is charged even before switching off the switch T2 to the instantaneous voltage of the AC voltage source 10.
  • the final state of charge of CS1 is reached after 8 microseconds, so remain 2 microseconds, during which the energy is stored in this circuit.
  • the switch T2 ie the switch is now in the non-conductive state, the stored energy in the aforementioned circuit flows through the freewheeling diode DF1 in the storage capacitor CS and is unloaded there. A backflow of energy from the storage capacitor CS to the output terminal K1 of the rectifier is prevented by the pumping diode DP1.
  • this circuit allows the operation of the load LD, in particular an ignition in the event that the load is a gas discharge lamp, without the interposition of a transformer.
  • a capacitor CS2 is now loaded during the turn-on time of the switch T1. Accordingly, a diode DS2 is to be provided in series with the capacitor CS2, but now both are reversed in their position relative to the output terminals of the rectifier 14. Similarly, a diode DP2 is connected between capacitor CS2 and switch T2 to prevent discharge of the storage capacitor CS.
  • Fig. 1c shows an embodiment using only one coupling capacitor CK2.
  • the coupling capacitor CK1 in its interconnection according to Fig. 1a or 1b perform the same function, which is to eliminate the DC component.
  • the coupling capacitors may preferably be used as film capacitors, the storage capacitors preferably be realized as electrolytic capacitors.
  • FIGS. 1a to 1c have shown a terminal of the load LD at the output terminals of half bridges is in Fig. 1d an implementation of the idea according to the invention is shown in a circuit with a full bridge. This further comprises the electrical switches T3 and T4.
  • Fig. 2 shows one opposite Fig. 1a alternative connection of a low-pass filter 12 'to the output terminals K1 and K2 of the rectifier 14'. While the embodiment shown provides for a parallel arrangement of the filter 12 ', it may also be connected in series to the output terminals K1 and K2. In a particularly simple embodiment, the filter 12 'may be realized in a parallel arrangement to the output terminals K1 and K2 by a capacitor, in a serial arrangement as a throttle.
  • Fig. 3 shows a particularly preferred embodiment in which the solutions according to the embodiments of Fig. 1a and Fig. 1b Both in terms of circuit implementation and in terms of operation are combined, that is, a withdrawal of energy from the AC voltage source 10 takes place both during the on-time of T2 and T1 of the obvious for the expert that the circuit according to Fig. 3 also with the variants according to the Figure 1C .
  • Fig. 1d and Fig. 2 can be realized.
